Harshana :
I have Item
and Address
classes:
public class Item {
String name;
List<Address> address;
}
public class Address {
String name;
String lane;
}
Suppose I have a item list and want to filter items that has lane as "lane1"
.
I try below but in Eclipse it shows:
"Type mismatch: cannot convert from Stream Address to boolean"
items.stream().filter(a->a.getAddress().stream().
filter(b->b.getLane().equals("lane1"))).collect(Collectors.toList());
Sweeper :
You can use anyMatch
on the inner stream:
items.stream().filter(a->a.getAddress().stream().
anyMatch(b->"lane1".equals(b.getLane()))).collect(Collectors.toList());
